Here is recap simple setup to get faster loads with 12ga sabots

& slugs, Example using break actions...., reaming chamber

in a 12ga break action to 3.5" with a 3.5" 12ga reamer, that isn't

something needing special order, and use 3.5" plastic cases , or

get 3.5" brass cases made. With mag shotgun primers and

our slower powder loads you can get a quarter more speed,

which gives 50% more energy...
